UniProtKB/Swiss-Prot for MSL2 Gene

Component of histone acetyltransferase complex responsible for the majority of histone H4 acetylation at lysine 16 which is implicated in the formation of higher-order chromatin structure. Acts as an E3 ubiquitin ligase that promotes monoubiquitination of histone H2B at Lys-35 (H2BK34Ub), but not that of H2A. This activity is greatly enhanced by heterodimerization with MSL1. H2B ubiquitination in turn stimulates histine H3 methylation at Lys-4 (H3K4me) and Lys-79 (H3K79me) and leads to gene activation, including that of HOXA9 and MEIS1.
